TOALL WHOM IT MAYCONCERN:

Be it lcuowu that I, HENRY HOLCOLlB, of Patines-villain the county of Lake, and Sta'te of Ohio, have invented an Improved Automatic Feed for Vapor-Pans, die.; and I do hereby declare that the following is a full and exact description thereof, reference being had `to the accompanying drawings, in which Figure 1 is an elevation representing the exterior appearance of my said automatic feed; and

Figuref, a vertical central section of the same. i I

The letters of reference indicating similar parts in both fIgures.

f'lbis invention is designed to be euployed in connection with the vapor-pansof hot-air furnaces used for warming buildings. It is also adapted for sorghum-evaporators, and for all other processes that require the wat-er or other fluids tobe supplied 11s-evaporation goes on. It is` automatic or self-acting, and lwill keep up the supply, fast or slow, without further attention;A

My said improved automatic feed consists of a reservoir, to the bottom of which is attached a feed pipe, communicating with its interior, and nu air pipe which passes through it and the top thereof, over which it bends and passes again intouthe bodyot' the reservoir. Attached' to the top ofsaid reservoir is a neck or short pipe, supporting a filler; thisneck is provided with a. stop-cock, as also is the feed pipe before mentioned. Therlou'er ends f the said air and feed pipes are open, and are placed within the' vapor-pan or evaporator, so thatnvheu the level of thewater or other fluid falls below'- the open end of the said air pipe, air will enter and pass up into the vacuum, und cause the water to descendthe feed pipe, as will he explained. v

A, fig. l, is a reservoir or body, and B a iller. For common purposes the lsaid reservoir and filler may be of iin-plate, but for particular usos it is designed to have the body of said' reservoir constructed of glass, Vso that the quantity of the fluid can be readily noticed at any time. C is a feed pipe for supplying the water, Src., to the vapor-pan D. It is secured to the bottom ofthe body of the reservoir, und is provided withl a .stop-cock E, as shown. The air pipe F,'asrwill be secn, passes through the interior of the body ofthe reservoir, and `comes cut-,at the top G, over which it bends, and returns again inte the interior. The llerB is supported above the top G, and communicates .vith the inside ofthe reservoir by a short pipe, H, in which is a stop-cock, I. The said pipes C'F and H are made of any suitable metal, and maybe lined or coated on the inside it' required. The vapor-pau D has a waste pipe, J, attached to it, for the purpose of `providing against accident from any distri-rangement that might happen to the reservoir.

In using my said automatic feed with hot-air'fuinaces, the apparatus can be placed ou a convenient bracket, secured to the wall of the room above` the vapartment in which the furnace is kept, and connect with it by passing the feed and air pipes through the floor. 'It will thus be within convenient reach for relilling withoutthe trouble of going belowi i i By reference to the dotted lines and arrows of the figures, the operation of'- selffeeding will be readily understood. In fig. 2 the reservoir is represented filled 'with water to the line a b. This is done by closing the lower 'stop-cock E, and opening the upper one I, after which the upper one is again closed and the lower one opened; the water will now descend the supply-tube C, as seen bythe arrows in tig. 1, uhtil its level in tl1e vapor-pau D rises above the open en'd ofthe air tube F, as seen by the dotted lines c d, fig. 2, closing it and cutting ofi' the ingress of the air to the vacuum irthe reservoir, which stops the supply. When thel level of thewatc1',xeaches below the mouth of the said air tube F, air is again admitted, which passes up and over the top into the reservoir, thereby causing the water again to full down the supply pipe, until again cut oft'. by the closing-'ofthe mouth of the air tube us before. l i

What I claim as my invention, and desire to secure by Letters Patent, is- Y Vl. I claim the within-described automatic feed apparatus, consisting of the reservoir A, filler I3, supply pipes G and II, stop-cocks E and I, and air pipe F, arranged, combined, and operating as herein set forth und for the purpose specified. l i l 2. The combination of the said described apparatuswith vapor-pans, evapora'tors, tanks, and other articles used in the processes of the evaporation of' fluids.
